“…One example for this is the generalization to many atom sites in the unit cell. This was used among others for detailed studies on diluted magnetic semiconductor systems [294,319,320] and Heusler alloys [321,322]. Another recent extension of Butler's approach is the implementation of the KG equation within the framework of the NL-CPA by Tulip et al [318].…”

The modern version of the KKR (Korringa-Kohn-Rostoker) method represents the electronic structure of a system directly and efficiently in terms of its single-particle Green's function (GF). This is in contrast to its original version and many other traditional wave-function-based all-electron band structure methods dealing with periodically ordered solids. Direct access to the GF results in several appealing features. In addition, a wide applicability of the method is achieved by employing multiple scattering theory. The basic ideas behind the resulting KKR-GF method are outlined and the different techniques to deal with the underlying multiple scattering problem are reviewed. Furthermore, various applications of the KKR-GF method are reviewed in some detail to demonstrate the remarkable flexibility of the approach. Special attention is devoted to the numerous developments of the KKR-GF method, that have been contributed in recent years by a number of work groups, in particular in the following fields: embedding schemes for atoms, clusters and surfaces, magnetic response functions and anisotropy, electronic and spin-dependent transport, dynamical mean field theory, various kinds of spectroscopies, as well as first-principles determination of model parameters.

“…The dc conductivity of DMSs was first calculated by Turek et al [6] using the Kubo-Greenwood formula and coherent potential approximation (CPA) applied to the tight-binding LMTO method. They calculated the dc conductivity of (Ga, Mn)As for ferromagnetic, antiferromagnetic and local moment disorder (LMD) states.…”

The dc conductivity at T = 0 K of half-metallic diluted antiferromagnetic semiconductors and their super lattice is calculated by the use of the Kubo–Greenwood formula applied to the Korringa–Kohn–Rostoker (KKR) Green's function method and the coherent potential approximation in the framework of the local density approximation (LDA) of the density functional method (KKR-CPA-LDA). The calculated dc conductivity of superstructures composed of diluted antiferromagnetic semiconductors shows significant dependence on the magnetic structure of the superstructures. The mechanisms responsible for such behaviour are discussed on the basis of the first-principles calculation.
